Hi Linus, Thanks for running all these tests. Great to see early KMS helps. That tells me graphics mode on the adapter needs to be re-initialized after kexec'ing a kernel. Takao Indoh has been working on adding more code to stop all I/O from PCI devices before kexec'ing the new kernel and that code might help some, but I suspect kernel might be relying upon BIOS setting a sane graphics mode on the adapter before kernel gets control. This assumption is not going to work with kexec'd kernel, of course. I will keep an eye on Takao's work to see if that can help. -- Khalid -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
